我正在尝试mopidy-spotify使用以下方式安装插件：
sudo pip install -U mopidy-spotify
我收到了一堆错误：

有任何想法吗？我能够mopidy通过 pip 安装没有问题，但是当尝试获取任何插件时，我收到这些错误。

我按照 Jakuje 的建议安装了 libffi-devel 软件包。下次我运行 sudo pip install -U mopidy-spotify 时，它安装了一些依赖项，然后提出了这个块；

答案1
最有可能的是你只需要安装libffi-devel：
dnf install libffi-devel
它提供了缺失ffi.h和libffi.pc文件。
